Do any parasite cleansers work?

i need to know whether there is a product that will eliminate whats inside of me. im 99.99% i have a parasite infection and ive been sick with various health problems for 3 years now. when ive visited doctors and told them thats what i think is wrong they look at me like i belong in a mental institution and dont help me at all. ive had several blood tests, several doctors visit, a couple trips to a dermatologist for my skin (its horrible and red).......nothing. they cant tell me anything and my condition has not changed.

since doctors wont help, im by myself and have to figure it out on my own. ive taken wormwood capsules, done a colon cleanser (psyllium seed husks), and tried things like oil of oregano/apple cider vinegar/thyme. i need a solution that works otherwise the only way i may be taken serious is if i go to an ER (which i dont want to do).
